摘要
本文介绍了一种新的测定 Cl^-在水泥砂浆或混凝土中的扩散深度的方法.实验表明,它能简单、直观地显示出 Cl^-扩散或渗透深度,可分辨 Cl^-浓度为≥10μg/cm^2.据此可比较和评价不同材料的抗 Cl^-扩散或渗透的能力.该方法与直接测定 Cl^-扩散系数的方法有良好的相关性.
A new method for measuring the depth of chloride ion penetration or diffusion was presented in this paper.It shows that this method could simply display the depth of Cl^- penetration with the distinguishable chloride ion concentration about 10μg/cm^2.This method could be used to compare the resistance to Cl^- penetration of motars.Results show that the depths measured by this method well correlate with directly measured effective Cl^- diffusion coefficients.
